To all whom it may concern: 3

Be it known that I, ARTHUR WILLIs BRODE, a citizen of the United States,residing at Downers Grove, in the countyof Du Page and State ofIllinois, have invented a new and of to vary the combination and renewthe members when broken or injured. I

Further objects and advantages of this invention will appearin thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a view of a lock constructed in accordancewith my invention. Fig. 2 is a central section of the same. Fig. 3 is adetached view of the core and shacklearm. Fig. 4 is a similar view ofthe shacklepin and head. Fig. 5 is a detached detail view of one of thetumblers. Fig. 6 is a similar view of one of the spacing-rings. Fig. 7is a detail sectional view of the joint between the core-head andshackle-arm. Fig. 8 is a .vertical section of a modified form of thelock wherein a sliding shackle is employed. Fig. 9 is a transversesectional View on the line 9 9 of Fig. 8. Fig. 10 is a transversesection on the line 10 10 of Fig. 8 to show the means for securing theuppermost spacing-rim g in place.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawlngs.

In the construction illustrated in Figs. 1 to 7, inclusive, 1 designatesa core provided at one end with a preferably integral head 2, to whichis pivoted a shackle-arm 3, said core being provided at one side withagroove or halfbearing 4 for the reception of the shackle-pin 5. Thisshackle-pin carries a head 6, constructed to interlock with the free endof the shackle-arm and secure the latter against swinging movement whenthe shackle-pin is in its normal or locked position. In'the constructionillustrated the extremities of the head 6 and shackle-arm are rabbeted,and one is provided with a projection or stud 7 to fit in a depressionor socket 8 in the other.

Mounted for rotary adjustment upon the core is a series of spacedtumblers 9, between which are interposed spacing-rings 10, saidspacing-rings being preferably provided with exterior peripheral studs11, while the tumblers are provided with finger-holes 12 to facilitatethe adjustment thereof, said studs 11 serving as indicators by which thetumblers may be adjusted in manipulating the lock. The spacin g-rin gsare held from rotary movement upon the core by means of ears 13,projecting into a guide-groove 14 in the side of the coreopposite to thegroove or shackle-pin bearing, and the terminal spacing-ring adjacent tothe free end of the shackle-arm is held from axial displacement by meansof a removable pin 15, preferably threaded into a suitable opening inthe core.

Both tumblers and spacing-rings are provided with notches, respectivelynumbered 16 and 17, of which the former are permanently in registrationwith the groove or shackle-pin bearing, while the latter are adapted tobe arranged either in or out of registration, as it is desired torelease or look the shackle-pin, said shackle-pin being provided withnotches 18, adapted to be arranged in the planes, re- 1 spectively, ofthe tumblers for engagement by the inner peripheries thereofwhen thenotches of the tumblers are out of registration with the shackle-pinbearing.

An axial or longitudinal movement of the shackle-pin is necessary inorder to disengage the interlocking extremities ofthe shackle- .arm andthe head of the shackle-p'imbut it PATENT OFFICE.

ulating the lock and make it practically impossible for the same to beoperated when the combination is unknown, I provide the tumblers withone or more false notches 20, which are not extended wholly through thetumblers, but consist simply of depressions or indentations which areadapted, when arranged in the plane of the shackle-pin, to allow aslight axial movement thereof, but which are of insufficient depth toallow disengagement of the shackle-arm.

As a further means of preventing tampering with the lock I preferablyemploy a pivotpin 21 at the joint between the shackle-arm and thecore-head, which is threaded into place and is then swaged terminally,as shown in Fig. 7. The threads prevent the pin from being displacedaxially by striking the extremity thereof.

In the construction illustrated in Figs. 8 to 10,.inclusive, the samerelative arrangement of core 1, having a head 2, shackle-pin 5, tumblers9, and spacing-rings 10 is employed as above described. The shackle-loop22 is extended from the extremity of the shackle-pin and preferablyterminates in a stud 23, which fits in an auxiliary socket near theopposite side of the core. In this form of the improved look I alsoemploy a cap-plate 24, and as it is necessary to turn the shacklehavinga shackle-pin bearing, and a shacklepin provided with transversenotches, of a plurality i. of alternately disposed rotatable tumblersand fixed spacing-rings, the tumblers being reversible and provided withnotches to register with said bearing and also pin in order to swing theshackle-loop in the act of disengaging the latter from any object Iemploy a stop 15 for engaging a shoulder 25 on the shackle-pin. Thisshoulder extends entirely around the pin, as indicated in Fig. 8.Furthermore, in this modified construction of look I employ asecuring-pin 26, whichextends transversely through a suitable opening inthe core and terminally engages inrings, said securing-pin beingdisposed to engage the spacing-ring contiguous to and below theuppermost tumbler.

From the above description it will be seen that the false notches whichare arranged in the tumblers are disposed in both sides thereof, andthat otherwise the tumblers are made symmetrical, whereby they arereversible to change the combination, the projecting points or markersupon the exterior surfaces of the spacing-rings being preferablyarranged in alinement when the parts ofthe lock are assembled to serveas guides for the fingers of the operator, whereby the lock may bemanipulated in darkness. Furthermore, the projections on thespacing-rings maybe arranged in any desired relative positions, those inthe drawings being shown in pairs at opposite sides of the rings.

The advantage of the plurality of studs on the spacing-rin gs resides inthe fact thatthey serve to indicate to the operator the proper positionsof the contiguous tumblers, said tumblers being interchangeable, andhence requiring different studs to indicate their positions according tothe relative arrangement of said tumblers.

respectively with means for engaging the shackle-pin, and also withprojecting exterior finger-holds, and the spacing-rings being pro-,vided with a plurality of spaced projecting I studs forming indicatingpoints or markers for the contiguous tumblers, substantially asspecified.

2. In a lock, the combination with a core having a shackle-pin bearing,and a shacklepin provided with transverse notches, of a plurality ofalternately arranged tumblers Y and spacin g-rin gs having exteriorprojections for alinement, said tumblers being reversible to change thecombination and having means to engage the shackle-pin, substantially asj specified.

3. In a lock, the combination w1th a core provided in both side surfaceswith false 5 notches or depressions of less depth than the j tumblers,substantially as specified.

weirdly-extending ears 27 on the spacinghavinga shackle-pin bearing, andalternatelyarranged tumblers and spacing-rings mount- 4. In a lock, thecombination with a core ed upon the core, said tumblers being providedwith notches registering with said bearing, of a shackle-pin providedwith transverse notches for engagement by the tumblers, a

securing-pin arranged in the core contiguous to one of the terminalspacing-rings to hold .the latter in place, and a shoulder on theshackle-pin in the path of which the extremity of said securing-pin isarranged, to limit the axial movement of the shackle-pin, substantiallyas specified.

5. In a lock, the combination of a core provided with an integral head 2and having a shackle-pin bearing parallel with its axis, rotatabletumblers fitted upon the core and provided with notches to register withsaid shackle-pin bearing, a shackle-pin fitted for axial movement insaid bearing and provided at the opposite end from said core-head 2 witha shackle-pin head 6, said heads being extended laterally in a commondirection from the core, means for limiting the axial movement of theshackle-pin, and a shackle-arm pivotally mounted upon the core-head andhaving an interlocking connection with the shackle-pin head, adapted tobe engaged and disengaged by the axial movement of the shackle-pin,substantially as specified.

6. In a lock, the combination of a core propin is extended, and to beconoealedthereby when the shackle-pin is in its normal position, and ashackle-arm pivotally mounted upon the core-head and having aninterlocking connection with the shackle-pin head, adapted to be engagedand disengaged by the axial movement of the shackle-pin, substantiallyas specified.

In testimony that I claim the foregoing as my own I have hereto affixedmysignature in the presence of two witnesses.
